You talk to the machinist.
FJM Manufacturing LLC is a precision machining shop at 48 Bridge Street, Nashua, New Hampshire, founded and run by Frederick John Martin — a trained Tool and Die Maker with 15+ years on the controls.
Tolerances to ±0.0001″ · No minimum order · Next-business-day quotes
Frederick trained as a Tool and Die Maker at Solar Turbines, working to tolerances as tight as ±0.0001″ and developing his skills in GD&T. At AMETEK he specialised in injection mould making, working with high-performance alloys and heat treatment. Across 15+ years he has run ProtoTrak mills, wire EDM, vertical turret lathes and surface grinders, and has built everything from turbine tooling to custom mould inserts.
He founded FJM Manufacturing to bring that toolmaker’s approach to precision machining — custom fixtures and workholding designed in-house, tolerances to ±0.0001″ on critical features, 100% inspection on every part, and no job too small.
The person quoting your part is the person machining it. Technical questions get technical answers, on the phone.
Awkward parts other shops decline are usually a workholding problem, and workholding is what a toolmaker does.
One piece is a real order. Prototypes and single replacements are core business, not an inconvenience.
The shop is in Nashua, New Hampshire, minutes from the Massachusetts line, and serves customers across New Hampshire, Massachusetts, Maine and Vermont — including Manchester, Merrimack, Hudson, Lowell and Greater Boston.
Open Monday through Friday, 6:00 AM to 5:00 PM. Parts can be dropped off and collected.
There is no minimum order quantity. A single prototype, a one-off replacement, or a repair part is a real job here.
Quotes come back the next business day. Rush service is available, including next-morning turnaround on suitable jobs. The shop opens at 6:00 AM Monday through Friday.
Tolerances to ±0.0001″ on critical features. Every part is inspected against print before it ships — 100% inspection, not sampling — on a granite surface plate with a TESA height gauge.
Yes. Anodizing, plating, heat treatment and passivation are managed on your behalf, so parts arrive finished rather than as raw machined blanks. Light assembly is also available.
